A device for rescue and emergency assistance to victims of emergency situations of war and peace. The complex contains a portable transformed pressure chamber with a life support system, an air conditioning system, a gas purification system, a system for monitoring the composition of the gas medium and microclimate parameters in the compartments, an electrical supply system, a video surveillance system consisting of several video cameras, one for each compartment of the base element and at least at least one, directed to the premises of the barocomplex. The invention allows more complete research work in hyperbaric conditions and under water, including the provision of qualified medical assistance to persons affected by depressurization of an underwater vehicle (RF Patent No. 2392914 IPC A61G 10/02).

Oxygenobarotherapy in a multi-seat treatment chamber compares favorably with a single pressure chamber:

- the air environment in which the patient is located;

- the possibility of using treatment regimens with air breaks;

- inhalation of pure oxygen, not contaminated with endogenous impurities;

- the use of moistened oxygen;

- the possibility of being in a pressure chamber together with a patient of medical staff;

- increased comfort.

Known pressure chamber for oxygen barotherapy, containing a housing inside which are equipped with places for patients, compression and decompression systems, breathing apparatus, which contains an oxygen source operating in a closed cycle and containing an oxygen source associated with an oxygen humidifier, an oxygen mask, with inspiration valves and exhalation, regenerative cartridge, respiratory capacity, corrugated inhalation and exhalation tubes (RF Patent No. 1202579 IPC A61G 10/02).

A disadvantage of the known devices is the complexity of the design, the high cost of the procedures, the difficulties with the purification of oxygen from impurities.

The purpose of the utility model is to simplify the design, reduce the cost of procedures, and improve the quality of treatment.

The goal is achieved in that the pressure chamber contains a housing inside which there are places for patients, compression and decompression systems, breathing equipment, including an oxygen source, a corrugated inspiratory tube and an inspiratory valve in an oxygen mask connected to it through a humidifier, an exhalation valve with a corrugated tube expiration, while in the chamber body contains the intake and exhaust lines, an oxygen storage device connected to the intake line through a flow regulator (rotameter) and a humidifier with an oxygen source with bottom side and with corrugated inspiration tubes on the other side; an exhaled air collector connected on one side through an exhaust line with an external atmosphere and with corrugated exhalation tubes on the other hand; the oxygen source is an oxygen concentrator installed outside the chamber.

In FIG. 1 shows a General view of the device.

The pressure chamber contains a housing (1), inside which there are equipped places for patients (2), compression systems (3) and decompression systems (4), breathing equipment, including an oxygen source (5), a corrugated tube connected to it through a humidifier (6) the inhalation valve (7) and the inhalation valve (8) in the oxygen mask (9), the exhalation valve (10) with the corrugated exhalation tube (11), while the inlet chamber (12) and the outlet (13), the oxygen storage ( 14) connected by an inlet line (12) through a flow regulator (rotameter) (15) and a humidifier (6) with a source oxygen (5) on the one hand and with corrugated inspiration tubes (7) on the other hand; a collection of exhaled air (16), connected on the one hand through the exhaust pipe (13) with the outside atmosphere and with corrugated exhalation tubes (11) on the other hand; the oxygen source is an oxygen concentrator installed outside the chamber (5).

The operation of the device.

Patients are placed inside the pressure chamber (1) of the pressure chamber on equipped places (2), providing them with a comfortable position, equipped with oxygen masks (9). Using the compression system (3), the intended mode is set indoors. Patients wear oxygen masks (9) Turn on an oxygen concentrator (5) - a device consisting of an electrical unit that separates oxygen from air chromatographically or based on the principle of electrochemical oxygen generation. Ambient air through a dust filter and then through a bactericidal filter enters an oil-free compressor, from where pressure falls into columns filled with zeolite. From the columns, air enriched with oxygen through the inlet line (12) enters the reservoir (14), passing through a flow regulator (rotameter) (15), a humidifier (6) and through the corrugated inspiration tube (7), the inspiration valve (8) enters the mask the space of the oxygen mask (9). Oxygen on the patient's inspiration enters the lungs. The exhaled air through the exhalation valve (10) through the corrugated exhalation tube (11) enters the exhaled air reservoir (16) and is discharged outside the pressure chamber through the exhalation line (13). At the end of the procedure, using the decompression system (4), normalize the pressure inside the pressure chamber, stop the flow of oxygen, remove oxygen masks (9)

Individual oxygen concentrators are widely used in different countries for the treatment of patients with chronic DN in outpatient and home settings. The most promising are concentrators that produce more oxygen from atmospheric air. The principle of operation of the oxygen concentrator is that compressed filtered atmospheric air is supplied to a "molecular sieve" consisting of balls of inorganic silicate (zeolite), where nitrogen molecules are adsorbed and oxygen molecules are passed through. As a result, the percentage of oxygen in the gas stream in the range of 0.5-5 l / min "molecular sieve" is 95-90%.

It is generally recognized that the use of oxygen concentrators is the most effective and cost-effective way of oxygen therapy. These devices, due to ease of use, complete safety, low noise, are most widely used for long-term controlled oxygen therapy of patients with chronic respiratory failure and at home, to increase the physical performance of athletes.
